Revealing: In the shot where Vader throws the Emperor into the pit, the Emperor is obviously a puppet, because he doesn't move at all.

Continuity: When the droids enter Jabba's throne room, in the shot facing the droids, they are not standing on the same part of the floor as in the previous shot. Also, R2-D2 is facing Jabba, but in the previous shot, he was facing C-3PO.

Continuity: During Luke and Vader's conversation on Endor, as Vader says, "That name no longer has any meaning for me," he is pointing the hilt of Luke's lightsabre at Luke's chest. In the next shot facing Luke, the hilt is nowhere to be seen, even though it should be, because of its position in the previous shot.

Revealing: Right before Luke leaps from the speeder bike to the scout trooper's speeder, there's a shot showing the front of the speeders. Notice the area surrounding the speeders in this shot. During the rest of the speeder bike chase, the speeders pass through this area several times, even though they are not flying in circles. This can be seen, for example, from the sunlight hitting the ground and the tree on the left side with a bush in front of it. Also, one of the shots where this area is seen is the shot before the speeders pass two more scout troopers, but the background has been flipped.

Revealing: During the speeder bike chase scenes, speeders bikes don't affect any vegetation, even though they're flying near the ground at incredible speed.

Continuity: When the Imperials are tricked into leaving the bunker, they are surrounded by Ewoks, and as the shot ends, if you look through the crowd, you can see that Han turns his head to his right. In the next shot, he's facing forward again.

Revealing: Special Edition: In the first shot of the Bantha herd crossing the Tatooine desert, the second Bantha from the left has no head. Only the horns are there.

Audio problem: After landing on Endor, Han says, "This whole party will be for nothing if they see us.", but his lips hardly move.

Audio problem: In the beginning of the space battle, a Mon Calamari says, "Admiral, we have enemy ships in Sector 47.", but his lips don't move.

Continuity: Widescreen version: When the captured rebels are led out of the bunker, C-3PO walks out from behind a tree. In the next shot, the tree is much bigger, and C-3PO is further away from it.

Continuity: In this film, the Imperial officers are all wearing the same rank insignia. This was not the case in "Star Wars" and "The Empire Strikes Back".

Continuity: During the transport to the Sarlacc Pit, in some shots, Chewbacca is standing on Han's right. In other shots, he is standing behind Luke and Han.

Other: After Leia knocks out one of the scout trooper who discovered her on Endor, the other trooper tries to escape, and Leia shoots his speeder. It crashes into a parked speeder, and if you watch it in slow motion, the speeder it crashes into starts to explode before it is hit.

Continuity: In the first shot of the hologram of Endor and the Death Star, the Death Star orbits Endor in an counter-clockwise direction. In the subsequent shots, the Death Star orbits in a clockwise direction.

Revealing: On Jabba's sail barge, Luke's hand is wounded before it is shot at.

Other: In the original cinema release, one of the subtitles for Jabba's conversation is incorrectly spelled - 'there will be no bargin'. This was corrected for the video release.

Continuity: When Lando says goodbye to Han, after Ackbar's speech, Lando's lapel pin/medal swiches shoulders several times.

Continuity: The Millenium Falcon lost its radar in the Death Star, but it is visible at the end.

Continuity: When Luke and Vader enter the Emperor's throne chamber, the stars behind him move really fast. Later, they move in a normal way.

Continuity: As Boba Fett nods to Boushh, his costume is reversed due to the negative being flipped. The easiest part of his costume to see this on is his antenna, which is on the left-hand side of his head, whereas normally it would be on his right.
